"Where were they going?"

"Blood Reserve t'ink--dunno."

Cameron sat smoking in silence. He was completely at a loss.

"Why go to the Bloods?" he asked of Jerry.

"Dunno."

Jerry was not strong in his constructive faculty. His powers were those of observation.

"There is no sense in them going to the Blood Reserve, Jerry," said Cameron impatiently. "The Bloods are a pack of thieves, we know, but our people are keeping a close watch on them."

Jerry grunted acquiescence.

"There is no big Indian camping ground on the Blood Reserve. You wouldn't get the Blackfeet to go to any pow-wow there."

Again Jerry grunted.

"How far did you follow their trail, Jerry?"

"Two--t'ree mile."

Cameron sat long and smoked. The thing was extremely puzzling. It seemed unlikely that if the Piegan band were going to a rendezvous of Indians they should select a district so closely under the inspection of the Police. Furthermore there was no great prestige attaching to the Bloods to make their reserve a place of meeting.

"Jerry," said Cameron at length, "I believe they are up this Sun Dance Canyon somewhere."

"No," said Jerry decisively. "No sign--come down mesef." His tone was that of finality.

"I believe, Jerry, they doubled back and came in from the north end after you had left. I feel sure they are up there now and we will go and find them."

Jerry sat silent, smoking thoughtfully. Finally he took his pipe from his mouth, pressed the tobacco hard down with his h.o.r.n.y middle finger and stuck it in his pocket.

"Mebbe so," he said slowly, a slight grin distorting his wizened little face, "mebbe so, but t'ink not--me."

"Well, Jerry, where could they have gone? They might ride straight to Crowfoot's Reserve, but I think that is extremely unlikely. They certainly would not go to the Bloods, therefore they must be up this canyon. We will go up, Jerry, for ten miles or so and see what we can see."

"Good," said Jerry with a grunt, his tone conveying his conviction that where the chief scout of the North West Mounted Police had said it was useless to search, any other man searching would have nothing but his folly for his pains.

"Have a sleep first, Jerry. We need not start for a couple of hours."

Jerry grunted his usual reply, rolled himself in his blanket and, lying down at the back of a rock, was asleep in a minute's time.

In two hours to the minute he stood beside his pony waiting for Cameron, who had been explaining his plan to the two constables and giving them his final orders.

The orders were very brief and simple. They were to wait where they were till noon. If any of the band of Piegans appeared one of the men was to ride up the canyon with the information, the other was to follow the band till they camped and then ride back till he should meet his comrades. They divided up the grub into two parts and Cameron and the interpreter took their way up the canyon.

The canyon consisted of a deep cleft across a series of ranges of hills or low mountains. Through it ran a rough breakneck trail once used by the Indians and trappers but now abandoned since the building of the Canadian Pacific Railway through the Kicking Horse Pa.s.s and the opening of the Government trail through the Crow's Nest. From this which had once been the main trail other trails led westward into the Kootenays and eastward into the Foothill country. At times the canyon widened into a valley, rich in grazing and in streams of water, again it narrowed into a gorge, deep and black, with rugged sides above which only the blue sky was visible, and from which led cavernous pa.s.sages that wound into the heart of the mountains, some of them large enough to hold a hundred men or more without crowding. These caverns had been and still were found to be most convenient and useful for the purpose of whisky-runners and of cattle-rustlers, affording safe hiding-places for themselves and their spoil. With this trail and all its ramifications Jerry was thoroughly familiar. The only other man in the Force who knew it better than Jerry was Cameron himself. For many months he had patroled the main trail and all its cross leaders, lived in its caves and explored its caverns in pursuit of those interesting gentlemen whose activities more than anything else had rendered necessary the existence of the North West Mounted Police. In ancient times the caves along the Sun Dance Trail had been used by the Indian Medicine-Men for their pagan rites, and hence in the eyes of the Indians to these caves attached a dreadful reverence that made them places to be avoided in recent years by the various tribes now gathered on the reserves. But during these last months of unrest it was suspected by the Police that the ancient uses of these caves had been revived and that the rites long since fallen into desuetude were once more being practised.

For the first few miles of the canyon the trail offered good footing and easy going, but as the gorge deepened and narrowed the difficulties increased until riding became impossible, and only by the most strenuous efforts on the part of both men and beasts could any advance be made.

And so through the day and into the late evening they toiled on, ever alert for sight or sound of the Piegan band. At length Cameron broke the silence.

"We must camp, Jerry," he said. "We are making no time and we may spoil things. I know a good camp-ground near by."

"Me too," grunted Jerry, who was as tired as his wiry frame ever allowed him to become.

They took a trail leading eastward, which to all eyes but those familiar with it would have been invisible, for a hundred yards or so and came to the bed of a dry stream which issued from between two great rocks.

Behind one of these rocks there opened out a gra.s.sy plot a few yards square, and beyond the gra.s.s a little lifted platform of rock against a sheer cliff. Here they camped, picketing their horses on the gra.s.s and cooking their supper upon the platform of rock over a tiny fire of dry twigs, for the wind was blowing down the canyon and they knew that they could cook their meal and have their smoke without fear of detection.

For some time after supper they sat smoking in that absolute silence which is the characteristic of the true man of the woods. The gentle breeze blowing down the canyon brought to their ears the rustling of the dry poplar-leaves and the faint murmur of the stream which, tumbling down the canyon, accompanied the main trail a hundred yards away.

Suddenly Cameron's hand fell upon the knee of the half-breed with a swift grip.

"Listen!" he said, bending forward.

With mouths slightly open and with hands to their ears they both sat motionless, breathless, every nerve on strain. Gradually the dead silence seemed to resolve itself into rhythmic waves of motion rather than of sound--"TUM-ta-ta-TUM. TUM-ta-ta-TUM. TUM-ta-ta-TUM." It was the throb of the Indian medicine-drum, which once heard can never be forgotten or mistaken. Without a word to each other they rose, doused their fire, cached their saddles, blankets and grub, and, taking only their revolvers, set off up the canyon. Before they had gone many yards Cameron halted.

"What do you think, Jerry?" he said. "I take it they have come in the back way over the old Porcupine Trail."

Jerry grunted approval of the suggestion.

"Then we can go in from the canyon. It is hard going, but there is less fear of detection. They are sure to be in the Big Wigwam."

Jerry shook his head, with a puzzled look on his face.

"Dunno me."

"That is where they are," said Cameron. "Come on! Only two miles from here."

Steadily the throb of the medicine-drum grew more distinct as they moved slowly up the canyon, rising and falling upon the breeze that came down through the darkness to meet them. The trail, which was bad enough in the light, became exceedingly dangerous and difficult in the blackness of the night. On they struggled painfully, now clinging to the sides of the gorge, now mounting up over a hill and again descending to the level of the foaming stream.

"Will they have sentries out, I wonder?" whispered Cameron in Jerry's ear.

"No--beeg medicine going on--no sentry."

"All right, then, we will walk straight in on them."

"What you do?" inquired Jerry.

"We will see what they are doing and send them about their business,"

said Cameron shortly.

"No," said Jerry firmly. "S'pose Indian mak beeg medicine--bes' leave him go till morning."

"Well, Jerry, we will take a look at them at any rate," said Cameron.

"But if they are fooling around with any rebellion nonsense I am going to step in and stop it."

"No," said Jerry again very gravely. "Beeg medicine mak' Indian man crazy--fool--dance--sing--mak' brave--then keel--queeck!"
